Which functions in our program Actual Title Buttons do you use most?

The Stay Always-on-Top button is the only feature I plan to use and it's very useful:
it's very accessible (one click in all programs) and visually shows if it is in or not.

With which applications on your PC do you use Actual Title Buttons?

It is very useful for reading newsletters in Outlook Express: click to Stay Always-on-Top then
I can click links of interest and have them all open in the background in separate tabs in my
browser (Opera): saves scrolling back to them if I decide to carry on reading the newsletter.
